Can't connect to Gateway

Hi all, I’m pretty new to LoRa and Chirpstack but I have followed the whole installation guides and Installed my NS/AS and gateway on my server.
I have a RisingHF gateway router (rhf2s024), and I believe all of my settings are correct but my Chirpstack gateway keeps saying “Last Seen - Never”.

On the Gateway, I have the Packet Forwarder enabled with the following:

I have opened the port 1700 on both my router and on the server-side.
There is very limited information on this gateway, so I am not sure if my setting are correct.
It also gives me the option of Enabling an “IOT Server Bridge”, but I’m not sure if this should also be enabled or only the Port Forwarder.

Any assistance will be greatly appreciated!!

IOT Server Bridge

This is what the settings look like for the IOT Server Bridge. The MQTT is the standard URL that comes with unit, but I have changed the HTTP to my server. I’ve tried this with being enabled and disabled with no success. The MQTT only accepts a tls URL.
Thanks again.

Shouldn’t Server Address be just the IP address of the ChirpStack Gateway Bridge server?
